Mirror 2 smart tvs macbook air late 2013

I purchased the thunderbolt to hdmi works perfect. Possible to make my other TV Mirror somehow to the other one. I day trade on thr stock market. And I really need 2 tvs not just the one I have thr thunderbolt outlet to 1 TV. Or, do they make a cable with 2 male hdmi on the end or 1 hemi male and maybe really cables for the 2nd one ? Thank you so very much for your time, thanking ou in advance
